- Gizzard Impaction
- Intestinal Impaction
- In waterfowl, generally secondary to conditions such as Lead Poisoning, Gizzard Worm Infection, and Foreign Body Ingestion
(including fish hook and line ingestion - see: Hook and Line Injury).
- Also reported in wild Canada geese (Branta canadensis - Canada
- with no obvious sign of a causative agent (B15).
- while grazing lush spring pasture - described as 'impaction due to food
- proventricular impaction associated with nonsuppurative encephalomyelitis
and ganglioneuritis (J1.27.w6).
- May occur in ducklings or goslings due to ingestion of tough vegetable
matter or various foreign bodies including hay, straw, paper or shavings if used for as a
food in the gastro-intestinal tract, usually in the oesophagus sometimes in the
proventriculus, gizzard or intestines (J36.41.w1, J7.30.w2, J1.27.w6, J14.19.w1, B11.34.w2, B15).
- Free-living Canada geese Branta canadensis associated with nonsuppurative
encephalomyelitis and ganglioneuritis (J1.27.w6).
- Free-living whooper swan Cygnus cygnus with lead poisoning (J3.111.w2).
- Fulvous whistling-duck Dendrocygna bicolor (intestine), Florida
duck (mottled duck) Anas fulvigula (J7.4.w1).
- Goosander (common merganser) Mergus merganser, cinnamon teal Anas
cyanoptera, scaup Marila sp. (J7.6.w1).
- Carolina (wood duck) Aix sponsa and maned geese Chenonetta
jubata in a collection in the UK (J7.32.w1).
- Gizzard and/or proventriculus impactions associated with foreign body
ingestion in red-breasted mergansers Mergus serrator in a collection in the UK (J7.30.w2).
- In whistling ducks Dendrocygna spp. downies, juveniles and
adults in a collection in the UK (J7.33.w2).
- In ruddy duck Oxyura jamaicensis, Argentine ruddy duck (lake
duck) Oxyura vittata and white-headed duck Oxyura leucocephala
juveniles; also in downy stifftails, in a collection in the UK (J7.33.w3).
- Rarely recorded (1% of adults, 2% of juveniles/downies) in geese (Anser
spp. and Branta spp.) in a collection in the UK (J7.34.w1).
- Gizzard impaction recorded in adult and juvenile swans in a collection in
the UK (J7.43.w1)
- Free-living Canada geese Branta canadensis, due to food overload while grazing
lush spring pastures (J14.19.w1).
- Various free-living waterfowl, associated with gizzard lesions due to parasitism (J14.19.w1).
- Wild mute swans Cygnus olor and whooper swans Cygnus cygnus
associated with lead poisoning (J36.41.w1, J36.44.w1
- Wild mute swan Cygnus olor with nylon fishing wire obstructing
the gizzard (J36.44.w1).
- Wild lesser scaup Aythya affinis with impacted snail shells
occluding small intestine, on lower Detroit River (P10.28.w1).
- Canada geese Branta canadensis in Washington, USA (B15).
- Impaction was seen in five of 135
Grus canadensis - Sandhill
cranes at Patuxent Wildlife Research Center, 1966-1975: in three
chicks, death occurred from starvation with intestinal impaction
(dehydration and anaemia were also noted); an adult died from starvation
associated with oesophageal obstruction with a
bolus of chitinous exoskeleton and another crane died from starvation
associated with impaction of the gizzard with bedding material. (P87.1.w2)
- Impaction of the crop due to ingested carpet fibres (from carpet
used as substrate) occurred in a
leucogeranus - Siberian crane chick. (P92.1.w3)
- Treatment by surgical removal of impacted material from
the oesophagus has been reported (see: Oesophageal
Surgery of Waterfowl). N.B. The oesophagus must be sutured
securely in two layers (J3.111.w2, B11.34.w2).
